Today marks the three year anniversary of a huge plains tornado outbreak.

Posted on25. Mar, 2010 by Jesse.
Are you tired of popping anti-SDS pharmaceutical products? If so, this weekend offers a potentially paltry cold core event in SE KS and Western MO. The 00z GFS and NAM, as well as the 12z ECMWF are fairly synchronous in propelling an upper level cold core low eastward along the KS/OK border region from 06z [...]

Posted on19. Mar, 2010 by Jesse.
Today’s 12Z model runs have started to come into better agreement regarding the upcoming storm system that should move out of the Southern Plains and into the Ohio River valley by early Monday.

Posted on18. Mar, 2010 by Adam.
Looking into the forecasting crystal ball, there is growing evidence of a more active weather pattern across the central portions of the United States. Inherently, that will lead to the possibility of severe weather episodes across that same region. With a strong baroclinic zone setting up across the mid-section of the CONUS there is a [...]

Things did not pan out as expected, however, we were still treated to a decent light show and some beautiful structure. I may post a video of some lightning later on.

On the night of Wednesday, March 10, 2010, a line of severe warned storms developed in central Missouri and tracked ENE.

3/11/2010 Forecast – Isolated severe weather over IA and IL
Posted on09. Mar, 2010 by Skip.
I’m eyeing central IA into west central IL for possible cold-core like activity in the early afternoon including an isolated risk for large hail and tornadoes. The 12z NAM is in fairly good agreement with previous runs that an elongated area of low pressure at the surface is going to setup over central IA extending [...]
